Abstract: Color confinement and chiral symmetry specify some important territory forthe study of hadronic physics. Any hadron can be defined as a color-singletcomposite system of qurks and gluons, the fundamental fields of qcd, while thelandscape of the hadronic spectrum is dominated by the fact that two quarkflavors, u and d, are characterized by masses small compared to the fundamentalscale of this theory. Measurements sensitive to the orbital angular momenta ofthe color constituents of the nucleon display the interplay of chiral dynamicsand confinement in a unique manner. This pageant can be explored by anevaluation, within the context of the Georgi-Manohar chiral quark model, of thenormalization of the orbital structure functions and the normalization of theBoer-Mulders functions for different quark flavors. The resolution structuresin the chiral quark model represent an evaluation of Collins functions for aconfined system defined by the quantum numbers of the nucleon in theconstituent quark model. The orbital structure functions for antiquarks canalso be specified within the basic framework of this approach while thenormalization of the gluon orbital structure function requires some additionalassumptions.
